Eat this and perform

A guy walks into the pharmacy and says to the pharmacist, "I have three girls coming over tonight! I have never had three girls at once. I need something to keep me interested, and keep me potent."

The pharmacist reaches under the counter and removes a brown box with an "X" on it. "Here," said the pharmacist. "If you eat this you'll go wild and nuts."
"Great!" the guys says. "Give me three of them."

The next day the guy comes back into the pharmacy. He drops his pants and the pharmacist looks in horror at the guys tool. It's black and blue, and the skin is hanging off of it.

"That "X" stuff was great, but now I need some Ben-Gay (analgesic heat rub used to relieve muscle and joint pain)," the guy shouted.

"You're not going to put Ben-Gay on that are you?" asked the pharmacist.
